HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 465,944, dated December29, 1891.

Application filed December 29, 1890. Serial No. 376,077. (No model.)

To all whom it may concern:

Beit known that I, EDWIN G. MUMMERY, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan,

have invented a certain new and useful Im provement inHydrocarbon-Burners; and I declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to-the accompanying drawings, which form a part ofthis specification. My invention relates to certain new and usefulimprovements in a hydrocarbon-burner; and it consists of thecombinations of devices and appliances hereinafter specified andclaimed, and illustrated in the accompanying drawings, in which- Figure1 is a view in perspective. Fig. 2 is a vertical crosssection, and Fig.3 is a separate view of the overflow basin in section.

My invention has for its object more particularly the combination, witha hydrocarbon-burner, of a device for regulating and controlling thesupply of water admitted to the burner to generate steam to comminglewith the oil and vaporize it.

IIeretofore considerable difficulty has been experienced in burners ofthe class wherein oil and water are used, suitably commingled andvaporized for fuel, owing to the difficulty in properly controlling thesupply of water admitted to the burner. If too much wateris at any timeadmitted, the the will be put out. If too little water is admitted, theoil cannot be suitably vaporized. A regulating device is thereforedemanded which shall be even and uniform in its operation, so as toconstantly control the supply without variation and without thenecessity of attention being given thereto. My invention is designed toaccomplish this end, in connection with a burner essentially like thatembodied in United States Letters Patent granted to me December 16,1890, No. 4et2,693.

I carry out my invention as follows:

A and A represent two generating-chambers, into which water is admittedthrough a supply-pipe B entering one of said chambers. These chamberscommunicate, preferably at their extremities opposite the entrance ofthe supply-pipe, as shown, by a connecting-pipe a. In thesechamberssteam is generated.

C O are superheating-pipes communicating with the chamber A, as shown atc, and with .one another, as shown at c, and also with the chamber A, asshown at 0 The Water and generated steam thus pass through the chambersA A in passing to the superheaters O O.

C is an additional superheating-pipe communicating with the superheaterG, as shown at 0 and with amiXing-chamber D, as shown at 0 E is anoil-supply pipe leading into the mixing-chamber I). At or near theentrance of the oil, as will be seen, the steam is admitted tocornmingle therewith in a superheated condition to vaporize the oil andsupply the vapors of the steam thereto to facilitate combustion.

The mixing pipe or chamber D communicates with a burner-tube F, locatedwell under the vaporizing or generating chambers A A, so as to supplyheat as directly as possible thereto to facilitate the generation ofsteam. The communication of the chamber D with the tube F is shown at L.

G is a cover-plate, preferably employed to deflect the flame.

H is a trough onwhich the burner rests, so arranged that the drip of thetube F, when the burner is lighted, will drop thereinto. This trough isprovided with one or more openings 71. to admit air therethrough.

. To control the feed of water to the generating-chambers A A, I employan overflowcatch-basin K, as shown at Z), above mentioned. Thecommunication 1) may be located at the desired height in theoverflow-basin to insure a constant feed of water therethrough. Anyexcess of water discharged into the basin I freely overflows over therim of said basin into the catch-basin, from whence it is dischargedthrough the waste pipe. This construction obviously provides for aconstant supply of water in the basin I and prevents any surplus ofwater being admitted to the steam-generating chambers.

The surrounding catch-basin might be dispensed with and the waste-pipebe led upward through the base of the overflow-basin to a desired heightto receive the overflow; but the use of the catch-basin insures a freerdischarge of the surplus water from the overflow-basin. By means of thecontrollingvalve j the feed from the supply-pipe J into the basin can beregulated as desired. The beneficial results obtained thereby willreadily be seen. Itis evident in shutting off the supply of waterentirely by means of said cock or valvej, when it is desired toextinguish the fire, the basin remains filled just to the level of thebase of the channel in pipe B. Consequently in starting the fire againthe controlling-valve j can be operated to allow such a limiteddischarge from the basin through the pipe B into the generating-chamberthat the Water entering into the generating-chamber will be almostinstantly heated and thereby quickly converted into steam. Thisoperation greatly facilitates the starting of the fire and is found tobe a point of much importance.

lVhat I claim is 1. The combination, with a hydrocarbonburner providedwith a water-supply pipe 13, communicating therewith, of anoverflow-basin communieating with said pipe, and a main supply-pipe J toadmit water into said basin, substantially as described.

2. The combination, with a hydrocarbonburner provided with asupply-pipe, of an overflow-basin comm unicating with said pipe, awaste-pipe for the overflow from said basin,

and a main supply-pipe admitting the supply to said basin, substantiallyas set forth.

3. The combination, with a hydrocarbonburner provided with a supply-pipeB and main supply-pipe J, of an open overflow-basin located between saidsupply-pipes to receive the supply from the one and discharge it throughthe other, and a catch-basin located to receive the overflow from theoverflow-basin, said catch-basin provided with a wastepipe,substantially as set forth.

4. In a hydrocarbon-burncr, the combination of the steam-generatingchambers A A, superheating-pipes O C C communicating with one anotherand with the steanrgenerating chambers, a vapor-generating chamber D,communicating with the superheatingpipes, a burner communicating withthe yapor-generating chamber, an oil-supply p pe communicating with saidvapor-generating chamber, a water-supply pipe B and main supply-pipe J,and an overflow-basin located between said supply-pipes B J to receivethe water from the one and supply it to the other, substantially as setforth. I

5. In a hydrocarbon-burner, the combination of a steam-generatingchamber, superheating-pipes O 0' C communicating w th one another andWith the steam-generating chamber, a vapor-generating chamber D,communicating with the superheating-pipes, a burn er communicating withthe vapor-generating chamber, an oil-supply pipe communicating with saidvapor-generating chamber, a Water-supply pipe B and main supply-pipe J,an overfiow-basin located between said supply-pipes B and J to receivethe waterfrom the one and supply it to the other, and a valve located inthe supply-pipe J to control the feed therefrom into said basin,substantially as set forth.

In testimony whereof I sign this specification in the presence of twowitnesses.
